The piece that will attach the buckle has marks for hole punching.
The... (wait,… I need to go look up what the rod in the buckle is called)
prong.. (oh neeto, I learned something…parts of a buckle…frame, bar and prong)
I need to create a long hole for the prong to go through.
There is a pounding punch tool for creating that shape but I don’t use punches that require hammering cause they make too much noise for being in an apartment. I also would need to go find a heaver table and pound board…..too much extra extra.
This is a little more rustic way of creating the hole. I punch two bigger holes spaced apart.
Then to slice the portion out between the holes. Bevel the oblong hole and burnish it.
